Flat Color Wire provides more reflecting surface than round wire, to great effect, and also a little more strength. When used as ribbing on the body it cuts less into your dubbing,which enhances the ribbing effect even more. This way, Flat Wire combines the advantages of tinsel and the strength of wire! This universal sized Medium Flat Wire is excellent for small to big patterns such as nymph, lake flies and streamers. 16 meters (17 yards) per spool.
